Obesity appears to be a problem worldwide affecting millions of people in many developed countries.
According to the the National Center for Health Statistics in the U.S. obesity among adults has risen during the past 20 years to such an extent that now 60 million people over 20 years of age are now considered obese.
That equates to 30 percent of the population.
Of even more concern the percentage of young people who are overweight has more than tripled since 1980.
There are now more than 9 million children and teenagers aged 6-19 years, 16 percent, who are considered overweight.
These significant increases in the rates of those who are overweight or obese is a major concern because it has implications for the health of the American population.
Being overweight or obese considerably increases the risk of many diseases and health conditions such as hypertension, type 2 diabetes, coronary heart disease, stroke, gallbladder disease, osteoarthritis sleep apnea and respiratory problems and endometrial, breast, and colon cancer.
Many experts believe there are a range of reasons why obesity appears to be getting out of control and one of those reasons is that many people do not want to be told they are obese and many doctors are reluctant to tackle what can be a confrontational issue involving the whole family.
Among the medical profession there is debate over the language used to tell to tell children and teenagers they are fat, as labelling a child fat or obese is a sensitive issue.
The Centers for Disease Control and Prevention (CDC) has always favoured a diplomatic approach and refers to such children as "at risk of overweight."
Experts say such indirect terminology only serves to foster denial of a problem which now affects millions of U.S. youngsters.
The American Medical Association and other groups believe that the same terms, overweight or obese, should apply to, and be used with fat children.
British experts say any such move would make sense and would bring the U.S. in line with the rest of the world.
